  • Patent number: 9644454
    Abstract: A system and method for selectively actuating sliding sleeves in valve sub-members which are placed downhole in a wellbore, via one or more darts inserted into said wellbore, to thereby open a ports or ports in such sub-members to allow fracking of the wellbore. The dart is preferably coupled, or provided with coupling means to permit coupling, to a retrieval tool, which upon the retrieval tool being so coupled allows a bypass valve to be opened to thereby assist in withdrawing the dart from within the valve sub-members. Upward movement of the retrieval tool allows a wedge-shaped member to disengage the dart member from a corresponding actuated sleeve to allow the dart to be withdrawn from the wellbore.

  • Patent number: 9260952
    Abstract: Apparatus and methods are described for autonomously controlling fluid flow in a tubular in a wellbore. A fluid is flowed through an inlet passageway into a biasing mechanism. A fluid flow distribution is established across the biasing mechanism. The fluid flow distribution is altered in response to a change in the fluid characteristic over time. In response, fluid flow through a downstream sticky switch assembly is altered, thereby altering fluid flow patterns in a downstream vortex assembly. The method “selects” based on a fluid characteristic, such as viscosity, density, velocity, flow rate, etc. The biasing mechanism can take various forms such as a widening passageway, contour elements along the biasing mechanism, or a curved section of the biasing mechanism passageway. The biasing mechanism can include hollows formed in the passageway wall, obstructions extending from the passageway wall, fluid diodes, Tesla fluid diodes, a chicane, or abrupt changes in passageway cross-section.

  • Patent number: 9062518
    Abstract: A technique facilitates controlling fluid flows, such as fluid flows in a downhole well zone or zones. A flow control valve is employed to control a fluid flow and is operationally linked with an injection valve. Actuation of the flow control valve is used to automatically actuate the injection valve between corresponding positions allowing or blocking fluid injection. Closing or opening of the flow control valve thus results in a desired corresponding action of the injection valve, such as blocking flow or allowing flow through the injection valve.

  • Publication number: 20150068763
    Abstract: A downhole actuator typically for a downhole tool such as a valve, and typically for incorporation in a string of tubulars in an oil or gas well has a central axis with radially movable counterweights on opposite sides of the axis, which move radially outward to change the activation state of the actuator. The counterweights are supported by link arms which control the movement of the counterweights in response to centrifugal force created by rotation of the body, for example, during rotary drilling operations of the string. Radial outward movement of the counterweights typically transmits axial forces between sleeves at the upper and lower ends of the counterweights, so when the counterweights move radially outward, the upper and lower sleeves approach one another, which typically triggers the actuator.

  • Patent number: 8931566
    Abstract: An apparatus is described for controlling flow of fluid in a subterranean formation based on a selected characteristic of fluid flow, such as viscosity, velocity or density, as that characteristic varies over time. A pathway-dependent resistance assembly, such as a vortex chamber having two inlets and an outlet, provides varying resistance to fluid flow based on the ratio of flow from the inlets, the direction of flow as directed by the inlets, and the characteristic of the fluid. The incoming flow ratio is preferably determined by flowing fluid through a plurality of passageways having differing flow rate responses to fluid having differing characteristics. Fluid of a selected characteristic will encounter lesser resistance to flow across the system, while fluid of an un-favored characteristic will encounter greater resistance to flow. Thus, flow of well fluids can be autonomously restricted as the fluid characteristics change over time.

    Abstract: A valve seal assembly that provides for external pressure to be introduced to an energized seal of a valve, and compress the seal against a gate with enough force to block any paths where sand and chemicals would otherwise travel into valve body cavity or void. The external pressure introduced through pressure fitting makes the parts move like piston forcing the parts to compress together eliminating the machined tolerances or gaps required for the gate to be opened or closed. The compression can be provided by hydraulic pressure devices through injection ports. A separate valve seal assembly can be provided for each face of the gate and both assemblies can be activated when the fluids are flowing (open position) and an upstream valve seal assembly activated when the gate is in a closed position.

  • Publication number: 20140284060
    Abstract: The present invention relates to an inflow control device for controlling the flow of fluid into a tubular deployed in a wellbore comprising coupling between joints of tubulars. The inflow control device is mounted transversely through the coupling in any inflow can control devices the initial condition fluid flow between the exterior and interior of the tubular is prevented. As sufficient pressure is exerted upon the inflow control device from the interior of the tubular the inflow control device is actuated to allow fluid flow between the interior and exterior the tubular. A nozzle in the inflow control device allows fluid to pass at a preset rate.

  • Publication number: 20140262323
    Abstract: A downhole equalization assembly permits selective and remote opening of at least one downhole port or pathway to allow communication of pressure and/or fluid flow from inside a pressure containing system (such as, for example, a tubular pipe or other pressure containment system) to the outside of the containment system, or vice versa. A control device generating a magnetic field is inserted into a well and conveyed to a downhole equalization assembly. When the control device passes through an equalization assembly, an electrical current is generated that triggers an electronic counter. When a predetermined counter number is reached, a sliding sleeve is shifted, thereby exposing ports and/or pathways extending between the inside and outside of the equalization assembly. No physical contact or mechanical interference is required between the control device and any other components in order to actuate the equalization assembly.

  • Publication number: 20140251613
    Abstract: A valve and valve assembly are provided to allow opening of flow channels through the wall of a tubular by increasing and then decreasing pressure in the tubular. Slidable seals having different areas are used to apply an axial force to a shuttle in the valve in response to differential pressure across the valve when in the closed position. The axial force shears a pin, releasing the shuttle. A decrease of pressure in the tubular can allow the valve to open in response to a spring force. Multiple valves may be placed along a tubular string and the valves may be opened all at substantially the same time or at time intervals determined by pressures applied inside the tubular.
